GAS-LOG.

Specification of Letters Patent.

Patented Sept.4, 1917.

Application filed September 9, 1915. Serial No. 49,777.

To all whom it may concern:

Be it known that I, EUGENE S. BROWN, a citizen of the United States, residing at Oak Station, in the county of Allegheny and.

State of Pennsylvania, have invented certain new and useful Improvements in Gas-Logs, of which the following is a specification.

This invention relates to heaters and has special reference to that class of heaters known as gas logs, in which natural or artificial gas is utilized as a fuel and supplied through an opening located within a body or embedded in the material of a body composed of some non-burning material. The object of the present invention is to provide a heater of the described type in which the burner proper will be hidden from view either completely or to such an extent as to not detract from the ornamental appearance of the body of the device.

A further object of the invention is to provide means whereby the heat will be thrown out into the room in which the heater is located, and a further object of the invention is to provide means for permitting a circulation of air within the heater so that the body of the same will not be unduly raised in temperature and will, consequently, be protected from possible burning.

These stated objects of the vinvention and other incidental objects which will hereinafter appear are attained in such a device as is illustrated in the accompanying drawings, and the invention resides in certain novel features which will be first fully described and then more particularly pointed out in the claims following the description.

'In the accompanying drawings:

Figure l is a perspective view of a heater embodying my present invention;

Fig. 2 is a vertical longitudinal sectional view of the same;

Fig. 3 is a transverse sectional view thereof.

As clearly shown in the drawings, the body 1 is so shaped as to simulate a log'or section of a fallen tree and this body will preferably be composed of asbestos combined with other material of a plastic nature which may be readily molded into the desired shape. The body is hollow and approximately cylindrlcal, a long opening 2 being provided in one portion of the side of the body to permit the escape of the heat from the burner into the room. A metallic lining 3 is provided and this lining is spaced from the inner wall or surface of the body 1, except at the lower edge of the opening 2, as shown most clearly in Fig. 3. The lining has substantially circular ends 4 which are spaced from the end walls of the body and an air space 5 is thereby provided between the lining and the inner surface of the body. The upper longitudinal edge of the lining terminates at the rear of the upper edge of the opening 2, as shown at 6 in Fig. 8, and to the said edge of the lining I secure a metallic hood or shield 7 which is connected with the upper edge of the opening 2 by spaced lugs or ribs 8 whereby the air circulating between the inner surface of the body and the lining will be permitted to escape into the room. The burner 9 is locatedimmediately adjacent the inner edge of the hood or shield 7 and extends longitudinally of the body of the heater, being provided with a row of tips 10, which may be of metal or some refractory composition, as will be readily understood. The gas is supplied to the burner by an inlet pipe 11 which extends through the back portion of the heater and between the end of the same and the end of the lining, as shown clearly in Figs. 2 and 3, and is connected with the burner by a coupling 12 in the usual manner. The burner tips 10 will be very small and will be directed downwardly and forwardly so that jets of flame extending fromthe tips will not protrude through the opening 2 of the device in a dangerous or unsightly manner but will be barely visible,

so that they will have the appearance of small tongues breaking through the shell of a log. A series of openings 13 are formed very slightly below the horizontal plane of the upper edge of the opening 2 sothat it will not be visible to the casual observer when the device is in use, and the appearance of a burning hollow log will be created. It will also be noted that the burner is located culation of air currents be set up through the openings 13 and around through the heater to escape at the upper front end of the lining between the ribs or lugs 8 and through the opening 2 so that the air in the room containing the heater will be very quickly raised to the desired degree. I

My device is exceedingly simple in its construction and may be produced at a low cost. "When in use it will be found highly etticient for the purposes for which it is designed.

Having thus described the invent1on, what is claimed as new is: I

l. A heater comprising a substantially cylindrical casing having its opposite ends closed and provided in one side thereof with a longitudinal opening, a lining member eccentrically mounted within the casing and having an opening registering with the longitudinal opening in said casing, said lining defining an intermediate substantially crescentshaped heating chamber, there being draft openings formed in the casing and communicating with the heating chamber, a burner extending longitudinally of the lining member, and a deflector secured to the lining member at said burner and having its outer longitudinal edge provided with spaced lugs secured to the inner wall of the casing near the upper wall of the longitudinal opening therein and defining spaced passages communicat1ng w1th the heating chamber whereby to permit the heated air from said chamber to pass through the passages between the lugs into a room.

2. A heater comprising a substantially cylindrical casing having its opposite ends closed and one side thereof provided with a longitudinal opening, a lining member eccentrically mounted within the casing and defining a substantially crescent-shaped heating member, one longitudinal edge of the lining member being secured to the casing at the lower wall of the opening therein and the other edge of the lining member being spaced from the interior of the easing and terminating short of the upper longitudinal wall of the openlng in said casing, there being draft openings formed in the casing at the rear thereof and communicating with the crescent-shaped heating chamber, a burner disposed within and extending longitudinally of the lining member, and a deflector having its intermediate portion secured to the free end of the lining member and one longitudinal edge thereof arranged near the burner, the other longitudinal edge of the deflector being provided with spaced lugs rigidly secured to the inner wall of the casing at the upper wall of the longitudinal opening therein and defining spaced passages communicating with the interior of the crescent-shaped heating chamber.

3. A heater comprising a substantially cylindrical casing having its opposite ends closed and one side thereof provided with a longitudinally disposed opening, a lining member e'ccentrically mounted within the casing and having its opposite ends closed and one longitudinal edge thereof secured to the casing at the lower wall of the opening therein and its other edge spaced inwardly from the upper wall of said opening and also from the inner wall of the casing, said lining member defining an intermediate substantially crescent-shaped heatin chamber, there being draft openings formed in the casing near the bottom thereof and communicating with the heating chamber, a burner disposed within the lining member and extending longitudinally thereof, and a deflector extending the entire length of the lining member and having its intermediate portion secured to the lining member above the burner and its forward longitudinal edge provided with spaced lugs rigidly secured to the inner wall of the casing at the upper wall of the longitudinal opening therein and defining spaced passages communicating with the crescent shaped heating chamber.

4. A heater comprising a substantially cylindrical casing having its opposite ends closed and one side wall thereof provided with a longitudinal opening, the bottom of the casing being fiat and the rear wall thereof provided with spaced draft openings, a substantially cylindrical lining member eccentrically mounted within the casing and defining a substantially crescent-shaped heating member with which the draft openings communicate, one longitudinal edge of the lining member being secured to the casing at the lower wall of the longitudinal opening therein and the other longitudinal edge of the lining member being spaced from the inner wall of the casing and from the upper longitudinal wall of said open-.
